[0011] Preferably, there are multiple groups of bolt mounting holes, which are circumferentially distributed on the surface of the driving end cover body, and there are multiple groups of bolts, which are circumferentially distributed on the surface of the driving end cover body. The bolts correspond to the bolt mounting holes, and the bolts are clamped in the bolt mounting holes, and the two are movably connected.

[0012] Preferably, the bottom dimension of the storage groove is the same as the dimension of the baffle, the bottom dimension of the limit block is the same as the dimension of the arc-shaped groove, the dimension of the baffle is larger than the bottom dimension of the limit block, and the baffle corresponds to the storage groove, the baffle is clamped in the storage groove, and the two are movably connected.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] The bolt is rotated by using a tool. When the bolt disengages from the threaded hole on the starter surface, the limit block is stuck in the through groove to limit it, so the bolt will not fall off the annular block, so that the bolt is always in the bolt mounting hole, thereby preventing the bolt from being lost. The push plate is pushed to drive the transmission block to move, and the transmission block moves out of the square notch. Then the bolt is pulled. Since the inclined surface on the surface of the transmission block has the same slope as the inclined surface of the limit block, the transmission block will squeeze the limit block, so that the limit block moves horizontally and is stored in the storage groove. When the limit block is completely stored in the storage groove, the bolt can be pulled to remove the bolt from the bolt mounting hole, thereby realizing the disassembly of the bolt. This structure is simple and easy to operate, thereby preventing the loss of the main bolt of the drive end cover, avoiding affecting the next assembly, and is conducive to improving its use effect.

Since the limiting block 6 is clamped in the through groove 7 to limit it, the bolt 3 will not fall off from the annular block 5, so that the bolt 3 is always in the bolt mounting hole 2, thereby preventing the bolt 3 from being lost.

[0028] Embodiment 2:

[0029] On the basis of the first embodiment, in order to prevent the bolt 3 from being lost, a bolt mounting hole 2 is provided on the surface of the driving end cover body 1, an annular groove 4 is provided on the inner wall of the bolt mounting hole 2, a through groove 7 is provided on the arc surface of the bolt 3, a through hole 11 is provided on the bottom surface of the bolt 3, a groove 10 is provided on the inner wall surface of the through hole 11, and a square notch 9 is provided on the inner wall surface of the groove 10;

[0030] An arc-shaped notch 15 is provided on the surface of the end of the receiving groove 14, a baffle 12 is provided on the inner wall surface of the arc-shaped notch 15, a limit block 6 is fixed on the surface of the baffle 12, an inclined surface is provided on the end surface of the limit block 6, an inclined surface is provided on the end surface of the transmission block 16, and the inclined surface of the limit block 6 has the same slope as the inclined surface of the transmission block 16;

There are multiple groups of bolts 3, which are circumferentially distributed on the surface of the driving end cover body 1. The bolts 3 correspond to the bolt mounting holes 2, and the bolts 3 are clamped in the bolt mounting holes 2. The two are movably connected, which has a positioning effect on the installation of the bolts 3.

Since the inclined surface on the surface of the transmission block 16 has the same slope as the inclined surface of the limit block 6, the transmission block 16 will squeeze the limit block 6, so that the limit block 6 moves horizontally and is stored in the storage groove 14. When the limit block 6 is completely stored in the storage groove 14, the bolt 3 can be pulled out of the bolt mounting hole 2 at this time, thereby realizing the disassembly of the bolt 3. This structure is simple and easy to operate, thereby preventing the bolt 3 from being lost when the driving end cover body 1 is in use, avoiding affecting the next assembly, and being conducive to improving its use effect.
